I heard this on the morning news and thought I just had to bring it up here as the Pope has added a whole bunch of new sins that will send you to hell. Some of these I can somewhat understand, but a couple are just a little narrow-sighted in their intention:
“You offend God not only by stealing, blaspheming or coveting your neighbour’s wife, but also by ruining the environment, carrying out morally debatable scientific experiments, or allowing genetic manipulations which alter DNA or compromise embryos,” he said.
Morally debatable experiments? Does that mean anything you disagree with? The part about genetic manipulations of embryos could be understood from the point of view of making humanity into some sort of “perfect” vision of some deranged group or individual, but there are many valid reasons to manipulate the genome of an embryo such as in the case of hereditary genetic diseases. These sorts of blanket rulings are not going to be conductive to bringing people back to the Catholic church or convincing anyone that the church isn’t still sticking itself firmly in the dark ages.
Edit: Dr. Myers has some more commentary here.
